    I remember the day's of indexing the plugs so that the gap faced in between the two values. I still have all of the index washers I used to use when we were racing.

    J2X -

    Have you...say...called or e-mailed Joe Hunt..?
    Seems to me that that would be the most appropriate location for the best (I hate that word) answer..!

    If you call 'Joe Hunt'...ask for Roger Gleason, as Joe's been deceased these 15 years...
    but with that distributor, its common application would be preferable.
    The distributor doesn't know what engine lies below, and the HEI design was of GM origin...
    Good question, actually.

    Yes and no... the compression matters. More compression requires tighter gap.

    There are pros and cons about those magneto look-a-like units. I'd always have my previous unit along with me on a trip including the correct tools and a timing light.

    ... yet a lot of people open up the gap and/or use a hotter plug..

    Odd... I learned how to gap plugs from the msd instructions that came with my distributor... low compression motors they spec'd up to .050+ gap

    I agree, though wide spark plug gaps puts the stock points style rotor and cap under a lot of strain though, they have closer spacing of terminals and misfire or arcing can result.

    electronic distributers commonly gap between .040 and .044. Joe Hunt should have info on what the recommended gap is for that particular distributer. Tyr google; google is your friend.
